Brick-kiln



NITED STATES JAMES HENNEY, OF CLOVERPORT, KENTUCKY.

BRICK-KILN.

$PEGIFIGATION forming part of Letters Patent No. 477,364, dated June 21, 1892. Application filed February 27, 1892. Serial No. 423,063- (No model.)

T0 at whom it may concern.-

Be it known that I, JAMES HENNEY, a citizen of the United States, residing at Oloverport, in the county of Breckinridge and State of Kentucky, have invented certain new and useful Improvements in Brick-Kilns; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

The improvements relate to kilns for brick; but they may be extended in their application to kilns for burning clay and pottery of any form or style for which by suitable modifications my invention may be found applicable.

My invention consists in the following construction and combination of kiln, which will be first fully described, and the features of novelty then pointed out and claimed.

Figure 1 shows a sectional ground plan of a kiln embodying my invention. Fig. 2 is a detail sectional view.

A represents the outer wall of the kiln.

B shows a number of furnaces in the side and end walls of the kiln. These furnaces may be of any size or form suitable for one or more kinds of fuel desired to be burned.

C represents the flash walls extending around the inner sides of the outer walls, leaving an encompassing fine passage between the walls A and 0 common to each of the furnaces B, into which they all communicate.

D represents a series of fines extending across the kiln from side to side and are connected at either end with the chimneys E.

F are two fines in the bottom of the kiln at each end thereof. The intermediate portion of this flue is transverse of the kiln, from whence its opposite ends run diagonally into thecorner chimneys E in the four corners of the kiln.

G are the doors in the opposite ends of the kiln.

The fines D and F may be of any desired dimensions and may be arranged at any distance apart, according to the work required or dimensions of the kiln;

H represents gratings over the tops of the fines D and F. The gratings may be of any suitable pattern. The whole floor I of the kiln may have gratings or grids, if desired, both the floor and the tops of the fines being preferably on a common level. The fire from all the furnaces passes into the surrounding passage behind the flash-walls, which extend up to near the height of kiln. The products of combustion then strike the arched ceilingwall of the kiln and are deflected inwardly over the brick in the kiln. passes downwardly through the bricks and enters the fines D and F, from whence it passes to the chimneys E and out into the outer air. The chimneys are formed in the wall A between the furnaces B. The usual dampers are put in the chimneys to regulate the draft and the usual openings made on the side or top of the arch.

My kiln is a great improvement over all others. It will burn all kinds of clay to a uniform color from end to end and from top to bottom. My kiln is also very economical with fuel and accomplishes its work in the shortest practicable time, the draft being very free and good.

By the employment of the peculiar shaped diagonal fines F, in connection with the transverse fines, I am enabled to secure a much more perfect and uniform distribution of the heat within the kiln than in ordinary kilns and a much more complete combustion and draft.

L represents an intermediate longitudinal partition which'I place in the fines D and F to support the grid blocks or bars, which are of the shape shown, having widened ends, which rest upon the opposite walls of the fine.

I claim- A brick-kiln of the character described, consisting of an outer wall 'within which is arranged a series of furnaces in the sides and ends, a series of chimneys interposed be tween the furnaces, a series of intermediate transverse fines connected at their opposite The heat then a ends with the chimneys, fines at the end of In testimony whereof Iaffix my signature in the kiln, each having an intermediate transpresence of two Witnesses. verse portion and opposite diagonal extensions connecting with the corner chimneys of the JAMES HENNEY. 5 kiln, and a flash-wall extending around the Witnesses:
